Radar device mounting bracket assembly

Cross Reference to Related Applications

The present application claims priority from korean patent application No. 10-2022-0001696 filed on day 1 and 5 of 2022, which is incorporated herein by reference for all purposes as if fully set forth herein.

Technical Field

The present embodiment relates to a radar device mounting bracket assembly, and more particularly, to a radar device mounting bracket assembly that can achieve cost saving and simplification of an assembly process by reducing parts, and improve quality by reducing tolerances in the assembly process, and achieve better stability and accuracy in an angle adjustment process.

Background

The vehicle is equipped with an Electronic Control Unit (ECU) for electronically controlling various devices, and receiving information from sensors or switches mounted therein/thereon and processing the information to perform control functions, thereby improving stability and steering feel.

In particular, the vehicle has radar means for identifying surrounding objects, collecting information such as distance, relative speed or direction to the vehicle, and processing the information so that the electronic control unit can perform an anti-collision function or an accident avoidance function by identifying the distance between the vehicle and the surrounding objects. The radar apparatus needs to be installed at a correct position to be able to accurately recognize the distance to the surrounding object.

However, errors are unavoidable during the manufacture, assembly or installation of the radar apparatus on a vehicle. The conventional method of solving the error is to correct the direction of the radar apparatus by adjusting the angle of the radar apparatus after the radar apparatus is mounted on the mounting bracket.

However, too many components are conventionally used to adjust the angle of the radar apparatus, resulting in an increase in cost and complicated assembly. In addition, errors can be accumulated in the assembly process, excessive friction is caused in the angle adjustment process, the adjustment range is reduced, and high defect rate is caused.

According to the present embodiment, the radar apparatus mounting bracket assembly 100 includes: a first bracket 110 fixed to the vehicle body, and including a first coupling portion 111 and a second coupling portion 112 coupled to the radar device R and provided on a front surface 110a of the first bracket 110; the second bracket 120 including a third coupling part 121 coupled to the radar device R and coupled to the first bracket 110 to be movable forward or backward with respect to the first bracket 110; and an adjustment member 130 coupled to the first bracket 110 and the second bracket 120 to move the second bracket 120 with respect to the first bracket 110.

The following description refers to fig. 1. The radar device R is coupled to the vehicle body by the radar device mounting bracket assembly 100 according to the present embodiment. The first bracket 110 is coupled and fixed to a frame of a vehicle body. After the radar device R is coupled to the radar device mounting bracket assembly 100 according to the present embodiment, the angle of the radar device R may be adjusted by manipulating the adjustment member 130.

The first bracket 110 may include a first coupling portion 111 and a second coupling portion 112. The second bracket 120 is provided with a third coupling portion 121. The radar device R is coupled to the first to third coupling parts 111 to 121. The first coupling part 111 and the second coupling part 112 may protrude from the front surface 110a of the first bracket 110, and the third coupling part 121 may protrude from the second bracket 120 beyond the front surface 110a of the first bracket 110.

The second bracket 120 is movably coupled to the first bracket 110 forward and backward with respect to the first bracket 110. Accordingly, when the second bracket 120 moves forward or backward with respect to the first bracket 110, the height of the third coupling part 121 protruding from the front surface 110a of the first bracket 110 increases or decreases.

Movement of the second bracket 120 relative to the first bracket 110 may be performed by manipulating the adjustment member 130. In other words, after the radar device R is mounted to the radar device mounting bracket assembly 100 according to the present embodiment, the angle of the radar device R may be adjusted by manipulating the adjustment member 130. According to the present embodiment, the angle of the radar apparatus can be adjusted with such a simplified configuration, so that parts can be reduced, raw materials and manufacturing costs can be saved, and assembly can be simplified as compared with the conventional art. Errors in the assembly process can also be reduced to improve quality and achieve better accuracy and stability in the angle adjustment process.

According to an embodiment, the first, second and

third coupling parts

111, 112 and 121 are coupled to the radar device R through ball joints (ball joints) such that the angle of the radar device R may be adjusted by manipulating the adjustment member 130 to move the second bracket 120 forward or backward with respect to the first bracket. For example, as shown, the ends of the first, second and

third coupling parts

111, 112 and 121 have ball studs (ball bolts), and the radar device R may have sockets formed to receive the ball studs. The ball stud may be inserted into the socket so that the radar device R may be coupled to the first coupling part 111, the second coupling part 112, and the third coupling part 121. Accordingly, as shown in fig. 2, when the second bracket 120 moves forward or backward (left or right in the drawing), the radar device R may be tilted forward or backward with respect to a straight line (see reference numeral C) connecting the end of the first coupling part 111 and the end of the second coupling part 112.

The structure of the radar apparatus mounting bracket assembly 100 according to the present embodiment is described in more detail below with reference to fig. 3. According to an embodiment, the first bracket 110 may have a first through hole 311 passing through the first bracket 110 in the front-rear direction, and the third coupling part 121 may be inserted into the first through hole 311 and protrude forward with respect to the first bracket 110. Accordingly, the third coupling part 121 may protrude from the front surface 110a of the first bracket 110 through the first through hole 311 beyond the front surface 110a of the first bracket 110.

Further, according to an embodiment, the first bracket 110 may have a second through hole 312 passing through the first bracket 110 in the front-rear direction, and the second bracket 120 may have a protruding guide 122, the guide 122 being inserted into the second through hole 312 and supported by the first bracket 110. Since the guide 122 is inserted into the second through hole 312 and supported by the first bracket 110, the movement of the second bracket 120 with respect to the first bracket 110 can be stably performed.

In other words, as shown, the second bracket 120 may include a base portion, and be shaped such that the third coupling portion 121 and the guide 122 protrude forward from the base portion. The third coupling part 121 and the guide 122 formed on the base part are inserted into the first through hole 311 and the second through hole 312. The guide 122 may be inserted into the second through hole 312 to support the movement of the second bracket 120 with respect to the first bracket 110, and the angle of the radar device R coupled with the third coupling part 121 is adjusted as the second bracket 120 moves.

Further, according to an embodiment, as shown, a pair of second through holes 312 and a plurality of guides 122 may be provided. For example, when the second bracket 120 moves, an external impact may apply a torque to the second bracket 120 with the guide 122 as a central axis. If only one second through hole 312 and one guide 122 are provided, it may be difficult to offset the torque. Furthermore, the second bracket may vibrate, causing the radar device R to shift from its set position. In order to solve the problem, the first through hole 311, the second through hole 312, the third coupling part 121, and the guide 122 may be formed in a cross shape, and a plurality of second through holes 312 and a plurality of guides 122 may be provided, thereby effectively canceling the torque applied to the second bracket 120. The movement of the second bracket 120 may also be stably supported by the guide 122.

The adjustment member 130 for moving the second bracket 120 with respect to the first bracket 110 is described below. According to an embodiment, the adjustment member 130 may be screwed to the first bracket 110 or the second bracket 120 while being rotatably but axially fixedly coupled to the other bracket. Accordingly, as the adjustment member 130 rotates, the first bracket 110 or the second bracket 120 is moved along the screw in the axial direction of the adjustment member 130, but the other bracket is axially fixed so that the second bracket 120 can be moved relative to the first bracket 110. The user may adjust the angle of the radar device R by coupling the radar device R to the radar device mounting bracket assembly 100 according to the present embodiment and mounting a tool to the adjustment member 130 to rotate the adjustment member 130.

According to an embodiment, the first bracket 110 may have a first coupling hole 321, the second bracket 120 may have a second coupling hole 322, and the adjustment member 130 may be inserted into the first coupling hole 321 and the second coupling hole 322. The adjustment member 130 may be rotated while being inserted into the first and second coupling holes 321 and 322, and be screw-coupled to the first or

second brackets

110 or 120 while being rotatably but axially fixedly coupled to the other bracket.

According to an embodiment, as shown in fig. 3 and 4, the adjustment member 130 may be axially fixed relative to the first bracket 110 and threadedly coupled with the second bracket 120. Thus, when rotated, the adjustment member 130 is axially fixed together with the first bracket 110, and only the second bracket 120 moves forward or backward.

Further, the rotation of the adjustment member 130 with respect to the first bracket 110 may be supported by the bushing 410. For example, the first bracket 110 may be formed of plastic, and the adjustment member 130 may be formed of steel. In order to reduce friction and wear due to the rotation of the adjustment member 130, a bushing 410 may be provided between the adjustment member 130 and the first bracket 110.

Further, a fixing member 330 axially supported by the first bracket 110 may be coupled to the adjustment member 130 to axially fix the adjustment member 130 with respect to the first bracket 110. For example, the securing member 330 may be a snap ring.

According to an embodiment, as shown in fig. 5 and 6, the adjustment member 130 may be threaded with the first bracket 110 and axially fixed with respect to the second bracket 120. Accordingly, when the adjustment member 130 rotates, the adjustment member 130 together with the second bracket 120 may move forward or backward while the first bracket 110 is fixed.

Likewise, rotation of the adjustment member 130 relative to the second bracket 120 may be supported by the bushing 410. For example, friction and wear between the second bracket 120 formed of plastic and the adjustment member 130 formed of steel may be reduced by the bushing 410.

Further, a fixing member 330 axially supported by the second bracket 120 may be coupled to the adjustment member 130 to axially fix the adjustment member 130 with respect to the second bracket 120. For example, the securing member 330 may be a snap ring.

By the radar apparatus mounting bracket assembly thus formed, cost savings and simplification of the assembly process can be achieved by reducing parts, and quality can be improved by reducing tolerances in the assembly process, and better stability and accuracy in the angle adjustment process can be achieved.
